In many, sleep pathology may represent a symptom of the underlying neurodegeneration. However, a history of sleep disruption occurring years prior to onset of cognitive symptoms could represent a potential risk factor for AD. The aim of the present narrative review was to evaluate current evidence linking sleep disturbances with AD development and to understand the mechanisms that may contribute to this. Although the mechanisms by which poor sleep may contribute to AD genesis is not fully understood, emerging evidence linking disturbances in the sleep wake cycle with A\u03b2 deposition is shedding light on the relationship between sleep pathology and the subsequent development of AD. A\u03b2 burden appears to be enhanced by sleep-wake cycle disruptions and is suspected as being an important mechanism by which sleep disruptions contribute in AD development. Other mechanisms triggered by sleep disruption may also be involved in AD development, such as brain hypoxia, oxidative stress, circadian activity rhythms disturbances, overexpression of orexins, and blood-brain barrier impairment. Further understanding of the link between sleep disturbances and future development of AD is still needed before sleep disturbances are clearly marked as a preventable risk factor for AD. In these circumstances, early lifestyle interventions to help increase the quantity and quality of sleep may have a favorable outcome on decreasing the incidence of AD and this needs to be investigated further.<\/jats:p>","DOI":"10.3233\/jad-161287","type":"journal-article","created":{"date-parts":[[2017,5,26]],"date-time":"2017-05-26T14:46:39Z","timestamp":1495809999000},"page":"993-1002","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":45,"title":["Is Sleep Disruption a Risk Factor for Alzheimer\u2019s Disease?"],"prefix":"10.1177","volume":"58","author":[{"given":"Arthur Cassa","family":"Macedo","sequence":"first","affiliation":[{"name":"University of Sussex, Brighton, England, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sara","family":"Balouch","sequence":"additional","affiliation":[{"name":"Centre for Dementia Studies, Brighton and Sussex Medical School, Brighton, England, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Naji","family":"Tabet","sequence":"additional","affiliation":[{"name":"Centre for Dementia Studies, Brighton and Sussex Medical School, Brighton, England, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2017,5,26]]},"reference":[{"key":"e_1_3_2_2_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.neurobiolaging.2014.03.035"},{"key":"e_1_3_2_3_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.jsmc.2006.04.010"},{"key":"e_1_3_2_4_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.jalz.2012.11.007"},{"key":"e_1_3_2_5_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.bbadis.2004.08.014"},{"key":"e_1_3_2_6_2","doi-asserted-by":"publisher","DOI":"10.1126\/science.1072994"},{"key":"e_1_3_2_7_2","doi-asserted-by":"publisher","DOI":"10.1016\/S1474-4422(09)70299-6"},{"key":"e_1_3_2_8_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.jalz.2011.03.003"},{"key":"e_1_3_2_9_2","doi-asserted-by":"publisher","DOI":"10.2105\/AJPH.88.9.1337"},{"key":"e_1_3_2_10_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.jalz.2007.04.381"},{"key":"e_1_3_2_11_2","doi-asserted-by":"publisher","DOI":"10.1212\/WNL.0b013e31828726f5"},{"key":"e_1_3_2_12_2","doi-asserted-by":"publisher","DOI":"10.1126\/science.7638622"},{"key":"e_1_3_2_13_2","doi-asserted-by":"publisher","DOI":"10.1038\/376775a0"},{"key":"e_1_3_2_14_2","doi-asserted-by":"publisher","DOI":"10.1038\/375754a0"},{"key":"e_1_3_2_15_2","doi-asserted-by":"publisher","DOI":"10.1136\/bmj.309.6955.636"},{"key":"e_1_3_2_16_2","doi-asserted-by":"publisher","DOI":"10.1073\/pnas.90.20.9649"},{"key":"e_1_3_2_17_2","doi-asserted-by":"publisher","DOI":"10.1073\/pnas.90.5.1977"},{"key":"e_1_3_2_18_2","doi-asserted-by":"publisher","DOI":"10.1016\/S1474-4422(11)70072-2"},{"key":"e_1_3_2_19_2","doi-asserted-by":"publisher","DOI":"10.1016\/S1474-4422(05)70141-1"},{"key":"e_1_3_2_20_2","doi-asserted-by":"publisher","DOI":"10.1186\/1471-2318-8-36"},{"key":"e_1_3_2_21_2","doi-asserted-by":"publisher","DOI":"10.1097\/01.JGP.0000310778.20870.ae"},{"key":"e_1_3_2_22_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.sleep.2004.12.005"},{"key":"e_1_3_2_23_2","doi-asserted-by":"publisher","DOI":"10.1111\/j.1532-5415.2007.01543.x"},{"key":"e_1_3_2_24_2","doi-asserted-by":"publisher","DOI":"10.1111\/j.1532-5415.1982.tb01279.x"},{"key":"e_1_3_2_25_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.jpsychores.2004.02.001"},{"key":"e_1_3_2_26_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.jagp.2013.04.015"},{"key":"e_1_3_2_27_2","doi-asserted-by":"publisher","DOI":"10.2174\/15672050113109990134"},{"key":"e_1_3_2_28_2","doi-asserted-by":"publisher","DOI":"10.5665\/sleep.1732"},{"key":"e_1_3_2_29_2","doi-asserted-by":"publisher","DOI":"10.5665\/sleep.2802"},{"key":"e_1_3_2_30_2","first-page":"1537","article-title":"Self-reported sleep and beta-amyloid deposition in community-dwelling older adults","volume":"70","author":"Spira AP","year":"2013","unstructured":"SpiraAP, GamaldoAA, AnY, WuMN, SimonsickEM, BilgelM, ZhouY, WongDF, FerrucciL, ResnickSM (2013) Self-reported sleep and beta-amyloid deposition in community-dwelling older adults.
